Trying to break those chains

Putting in the miles ( 3.1)  for Thursday am run with a city skyline view. Today is going to be in the 90s and even before 6am I was having a hard time breathing. I was still feeling tired. Also, my period is on her way, so I feel the change in my body. The extra heat doesn't help. I'm always reminded to break the chains that try to hold you back. It may take awhile but eventually they will be broken .
